-$$f ( x ) = - 6 ( x + 8 ) ^ { 2 } - 7$$
A) $( - 8,7 )$
B) $( 8 , - 7 )$
C) $( - 8 , - 7 )$
D) $( - 48 , - 7 )$

Quizplus · Accepted Answer

The vertex form of a parabola is $f(x) = a(x - h)^2 + k$, where $(h, k)$ is the vertex. In the given equation, $f(x) = -6(x + 8)^2 - 7$, the vertex is $(-8, -7)$ by comparing it to the vertex form, recognizing that $h = -8$ and $k = -7$.
